Title
(EN) HEATING ELEMENT FOR HAIRDRYER
(FR) ÉLÉMENT CHAUFFANT POUR SÈCHE-CHEVEUX
Abstract
(EN)
An electric heating element (1) for hairdryer comprises a plurality of supporting plates (2) made of electrical insulating material, fixed to each other angularly spaced about a longitudinal main axis (X) and provided on respective external longitudinal edges (3) with first slots (4) suitable to receive and support at least a first resistive wire (11) wound around the supporting plates (2) so as to form a first heating winding (21); each supporting plate (2) further comprises on the respective external longitudinal edge (3) respective second slots (5) interposed between the first slots (4) and suitable to receive and support said first resistive wire (11) and at least one second resistive wire (22) wound around the supporting plates (2) to form a second heating winding (22); the first resistive wire (11) and second resistive wire (12) are able to generate heat when supplied by electric current.
(FR)
L'invention concerne un élément chauffant électrique (1) pour sèche-cheveux comprenant une pluralité de plaques de support (2) constituées de matériau isolant électrique, fixées l'une à l'autre angulairement espacées autour d'un axe principal longitudinal (X) et disposées sur des bords longitudinaux externes respectifs (3) avec des premières fentes (4) appropriées pour recevoir et supporter au moins un premier fil résistif (11) enroulé autour des plaques de support (2) de façon à former un premier enroulement chauffant (21) ; chaque plaque de support (2) comprend en outre sur le bord longitudinal externe respectif (3) des secondes fentes respectives (5) interposées entre les premières fentes (4) et appropriées pour recevoir et supporter ledit premier fil résistif (11) et au moins un second fil résistif (22) enroulé autour des plaques de support (2) pour former un second enroulement chauffant (22) ; le premier fil résistif (11) et le second fil résistif (12) sont aptes à générer de la chaleur lorsqu'alimentés par un courant électrique.
